This policy seems to impose exactly the same unfair application that Counsel
described in the summary for  global policy for returning v4 space to the
IANA[3]. Creating equal shares only means that equal allocations occur. It
still creates a severe need imbalance and potentially creates an unfair
advantage for smaller players that a /20 does fulfill their needs.

What's the projection of the impact of this policy on our final exhaustion,
total meltdown of IPv4 allocations utilizing in-region maximum[1] available
inventory[2]?

Perhaps we should instead make it less desireable to get PI and have anyone
who needs a /20 or less accept PA from their upstream?

A this time, I am not in favor of this policy.
